SOURCE /DOPPLER

        [ASTRO\]SOURCE /DOPPLER Type Value

    Can be used to be abe to take into account LSR velocities or redshift in
    the  frequency  coverage  computations  (NOEMA  and  PICOVELETA) without
    defining a full source (i.e. coordinates, V(LSR/G) and V(G/OBS)  veloci-
    ties are not computed.  In that case V(SOU/OBS)=V(S/LSR).

    Type can be REDSHIFT or LSR
    Value is the value (real) in the corresponding type of doppler.
